We would really like to see a user profile setting that allows each user to select a default folder/project that would be used automatically for any task the user creates where the task would currently be created without any folder/project assignment. Tasks created without any folder/project assignment land at the workspace root where they can very easily get lost.
Ideally (for us, anyway), the default for this new setting would be the user's Personal folder, with each user able to adjust their default as needed.
Use case 1: When creating a task from My Work, it's extremely easy to overlook the Add folders link, particularly when adding a number of tasks in rapid succession. When you press Enter after typing your task title (the intuitive way I've seen most of our users interact with this feature), the task gets created so you lose the chance to add the folder during task creation... you have to remember to click the Add folders link before you press Enter.
Use case 2: When adding multiple tasks that all belong in the same place from My Work, it's cumbersome to have to select the folder for each one. It's also cumbersome to leave My Work to find the tasks to use Mass Edit to change the folder assignments en masse.
